FIELD OF THE APPLICATION

The application relates generally to processing captured vehicle fluid for future use thereof.

BACKGROUND

Vehicles such as automobiles are often equipped with fluid reservoirs such as windshield wiper fluid reservoirs, radiator overflow reservoirs and the like. Depending on the type of vehicle and/or fluid composition(s) being used, a particular fluid reservoir may require periodic refilling as existing fluid is used up. Also, it is often necessary to replenish a particular reservoir with a fluid that is compositionally similar to the spent fluid.

Simply refilling fluid reservoirs with water that is captured from vehicular condensation may be sufficient in particular instances. However, water is often times an insufficient refill fluid for certain vehicle reservoir purposes. Therefore, a need exists for capturing fluid such as water from a vehicle, processing the fluid to provide one or more desired fluid product(s), and delivering the fluid product(s) to one or more specified vehicular fluid reservoir(s) for further use as desired.

Discussion of the System and Method

To better understand the novelty of the system and method of use thereof, reference is hereafter made to the accompanying drawings, in which like numerals represent like components throughout the several views. The following description is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

Variations of a simplified system 10 for processing captured condensed vehicular fluid are depicted in FIGS. 1 and 2. With reference to FIG. 1, the system 10 suitably comprises at least (1) a fluid reservoir 20, (2) an inlet member 12 in fluid communication with the fluid reservoir 20, the inlet member 12 being operationally configured to capture fluid from a vehicle surface 100, (3) a fluid circulation means 14 in fluid communication with the fluid reservoir 20, (4) a fluid volume sensor system 15 attached to the fluid reservoir in electrical communication with the fluid circulation means 14, (5) a treatment member 16 in fluid communication with the fluid circulation means 14 via conduit 22, (6) a power source 17 in electrical communication with the fluid circulation means 14 and fluid volume sensor system 15, and (7) an outlet 18 in fluid communication with the treatment member 16 via conduit 22. In operation, fluid is suitably conveyed via the fluid circulation means 14 from the fluid reservoir 20 through the treatment member 16 to the outlet 18 via conduit 22.

Without limiting the invention, the inlet member 12 is suitably operationally configured to receive collected fluid from a surface or basin of a vehicle, or to receive fluid condensate (hereafter “condensate”) from a condensate producing system of a vehicle. For example, as condensate accumulates on the surface of a vehicle's air conditioning evaporator coil (hereafter “A/C”) the inlet member 12 is operationally configured to receive condensate from the NC drip pan, where after the fluid may be stored in the fluid reservoir 20.

In one exemplary embodiment, the fluid reservoir 20 may be sealed to a vehicle surface 100 such as an NC drip pan in a manner effective to capture condensate, or the fluid reservoir 20 may be provided as an all-in-one condensate producing/condensate capture reservoir, e.g., a system 10 provided as part of the vehicle at the manufacturing stage. In another embodiment, the inlet member 12 and fluid reservoir 20 may be installed and fluidly connected to a pre-existing vehicle surface 100, e.g., a system 10 operationally configured for after-market use.

In still another embodiment, the inlet member 12 may comprise a collection pan in fluid communication with a fluid reservoir 20 wherein the collection pan set apart from a vehicle surface 100 is operationally configured to capture condensate as the condensate drops from the vehicle surface 100, the captured fluid thereafter flowing via gravity into the fluid reservoir 20. Hereafter, reference to a vehicle surface 100 will be discussed in terms of a vehicle A/C drip pan 100.

With reference to FIG. 2, the system 10 may further comprise one or more post-treatment reservoirs 24 in fluid communication with both the treatment member 16 and the outlet 18. The system 10 may also include a valve 30 located downstream from the fluid circulation means 14 operationally configured to regulate back flow of fluid in the conduit 22 toward the fluid circulation means 14. In this embodiment, the valve 30 is suitably positioned along the conduit 22 at a point between the fluid circulation means 14 and the treatment member 16. In another embodiment, both the valve 30 and the fluid circulation means 14 may be housed within the fluid reservoir 20, the valve 30 being suitably positioned along the conduit 22 between the fluid reservoir 20 and the treatment member 16.

The system 10 may further include one or more secondary treatment members (not shown). For example, one or more secondary treatment members may be operationally configured to act on fluid housed within the fluid reservoir 20 prior to being pumped to conduit 22. One or more secondary treatment members may be operationally configured to act on fluid housed within the second fluid reservoir 24 once the fluid is directed out through outlet 18. In still another embodiment, one or more secondary treatment members may be operationally configured to act on fluid flowing through a second conduit of the system 10.

As previously stated, the system 10 may be installed during the vehicle's manufacturing process or the system 10 may be installed in a vehicle as an aftermarket item. Thus, the configuration of the fluid reservoir 20 may vary as required based on the intended use of the system 10 and the design of the subject vehicle including space requirements thereof.

With reference to FIGS. 3 and 4, a simplified embodiment of a fluid reservoir 20 provided during a vehicle's manufacturing process is shown. In this embodiment, the fluid reservoir 20 suitably includes (1) a multi-sided outer housing 32 having a reservoir inlet 19 there through, (2) a first compartment 33 for storing captured fluid, (3) a second compartment 34 for housing a fluid circulation means 14, the second compartment 34 being separated by the first compartment 33 via (4) a solid barrier 36 having a reservoir outlet 21 there through, (5) a fluid volume sensor system 15 housed within the first compartment 33, and (6) an overflow outlet 23 in the outer housing 32 for the release of any unwanted fluid from the fluid reservoir 20. With reference to an automobile A/C 100, much more condensed water is generated than is ever requested for system 10 use. Thus, the overflow outlet 23 allows the fluid reservoir 20 to dump excess fluid from the system 10.

Turning to FIGS. 5A and 5B, an after-market embodiment of the fluid reservoir 20 is provided. In this embodiment, the fluid storing first compartment 33 of the fluid reservoir 20 is oriented below the second compartment 34. As shown, the second compartment 34 is operationally configured to house (1) a reservoir inlet 19, the reservoir inlet 19 being in fluid communication with inlet member 12 (not shown), (2) a fluid circulation means 14, (3) a check valve 30, (4) conduits fluidly connecting the inlet 19 to the first compartment 33, the first compartment 33 to the fluid circulation means 14, and the fluid circulation means 14 to the check valve 30, and (4) control circuitry 200. As shown in FIG. 6, the fluid reservoir 20 may be set within a corresponding bracket 25, the bracket 25 having one or more apertures 27 there through for receiving fasteners operationally configured to releasably attach the fluid reservoir 20 to a vehicle surface.

The reservoir inlet 19 may comprise any aperture configuration suitable for introducing fluid into the fluid reservoir 20. In the embodiment of FIGS. 5A-5B, the reservoir inlet 19 is in fluid communication with the drip pan 100 via inlet member 12, the inlet member 12 including a conduit fluidly sealed at a first end to the drip pan 100 and fluidly sealed at the second end to the reservoir inlet 19. In one embodiment, the drip pan 100, inlet member 12 and fluid reservoir 20 may be provided as a one piece mold construction during vehicle manufacturing for permanent attachment to the vehicle. In another embodiment, inlet member 12 and fluid reservoir 20 may be constructed as separate parts for further assembly and releasable attachment to a drip pan 100. As necessary and depending on the parts design and/or materials of construction, the drip pan 100, inlet member 12 and fluid reservoir 20 may be sealably assembled as is or using fittings via an adhesive material for sealing the fittings to the system 10 parts. Suitable fittings include, but are not necessarily limited to rubber grommets, rubber barbed fittings, plastic barbed fittings, and combinations thereof. A suitable adhesive includes, but is not necessarily limited to a two-part epoxy adhesive.

In the embodiment of FIGS. 3 and 4, the fluid reservoir 20 suitably has one or more mounting tabs 38 for receiving fasteners there through effective for releasably attaching the fluid reservoir 20 to a vehicle surface. Suitable fasteners include one or more threaded screws or other common removable fasteners. In addition, a sealing means such as a gasket 31 and the like may be included to effectively seal the outer housing 32 of the fluid reservoir 20 to the vehicle surface as desired.

Without limiting the system 10 to any particular materials of construction, the inlet member 12 and fluid reservoir 20 are suitably constructed from materials including, but not necessarily limited to those materials resistant to chipping, cracking, excessive bending and reshaping as a result of ozone, weathering, heat, moisture, other outside mechanical and chemical influences, physical impacts, and combinations thereof. In particular, the inlet member 12 and fluid reservoir 20 are suitably constructed from materials including but not necessarily limited to metals, polymeric materials, fiberglass, plexiglass, filled composite materials, and combinations thereof. Likewise, the inlet member 12 and fluid reservoir 20 may comprise any color or combination of colors. The inlet member 12 and fluid reservoir 20 may also be transparent and translucent as desired. In a particularly advantageous embodiment, the inlet member 12 and fluid reservoir 20 are each constructed of plastic.

Manufacture of the inlet member 12 and fluid reservoir 20 may be accomplished using known techniques including, but not necessarily limited to blow molding, injection molding, assembly of separate pre-formed individual components, and a combination thereof. The mode of manufacturing of the fluid reservoir 20 may be determined by one or more factors including, but not necessarily limited to (1) the type of vehicle, or in the case of an automobile the make and model thereof, (2) the intended use of the vehicle, (3) the anticipated retail cost of the system 10, (4) performance requirements of the system 10, and combinations thereof. The type of fluid reservoir 20 materials used may also depend on the type of fluid circulation means 14 employed, including the placement of the fluid circulation means 14 relative to the fluid reservoir 20.

Although not limited to a particular configuration, the fluid circulation means 14 may be (1) mounted adjacent the fluid reservoir 20, (2) releasably secured to the outside of the first fluid reservoir 20, or (3) housed within the fluid reservoir 20 as desired. Suitable fluid circulation means 14 include, but are not necessarily limited to pumps, siphoning devices or other pressure sources, blowers, propellers, push components to deliver captured fluid, and combinations thereof. For example, the fluid circulation means 14 may include an external or submersible pump. In one advantageous embodiment, the fluid circulation means 20 may include a positive displacement pump providing intermittent fluid flow from the fluid reservoir 20 to the outlet 18. In another particularly advantageous embodiment, the fluid circulation means 20 may include a centrifugal pump operationally configured to convey fluid from the fluid reservoir 20 to the outlet 18. Hereafter, the fluid circulation means 14 will be discussed in terms of a centrifugal pump (“pump 14”).

As depicted in FIGS. 3, 4, 5A and 5B, the pump 14 is suitably located within the second compartment 34 in a manner effective to seal the pump 14 from the captured fluid located within the first compartment 33 of the fluid reservoir 20. The second compartment 34 is effectively sealed off from the first compartment 33 via a wall 36. Suitably, the wall 36 comprises at least one aperture providing a fluid outlet 21 from the first compartment 33 to the second compartment 34. As shown in FIGS. 3 and 4, a pump inlet 39A is suitably attached at the outlet 21 providing for fluid communication there between. As shown in FIG. 5A, the pump inlet 39A is suitably fluidly connected to the outlet 21 via a first conduit 41A, and the pump outlet 39B is suitably fluidly connected to the valve 30 via a second conduit 41B. In operation, captured fluid is transferred through the reservoir inlet 19 and stored in the first compartment 33. Upon pump 14 activation, fluid is conveyed from the first compartment 33 through the pump 14 and valve 30 to the conduit 22.

With reference to FIG. 3, the pump inlet 39A is suitably sealed or otherwise mated to the outlet 21 via a coupling 29 or other connection means. Suitable couplings include, but are not necessarily limited to rubber couplings and brass couplings. In the embodiment of FIG. 5A, a male type pump inlet 39A and outlet 39B suitably provide for mating to the conduits 41A, 41B as typically found with conduit/nipple type fittings.

Turning now to the overflow outlet 23 of the fluid reservoir 20, the overflow outlet 23 may be located at any point along the outer housing 32 as desired. In one embodiment, the overflow outlet 23 may be located along the outer housing 32 at a point corresponding to the maximum fluid volume of the system 10. In another embodiment, the overflow outlet 23 may be located along the outer housing 32 at a point to ensure the availability of a fluid volume necessary to fill a particular second fluid reservoir 24. In another embodiment, the fluid reservoir 20 may further include a bottom plug 80 for emptying fluid there from. In still another embodiment, the fluid reservoir 20 may include only a bottom plug 80 with no overflow outlet 23.

In one exemplary embodiment of a system 10 requiring a maximum fluid volume of about 0.15 liters (about 5.0 ounces) including a fluid reservoir 20 having a maximum capacity of about 0.3 liters (about 10.0 ounces), the overflow outlet 23 may be positioned at a point along the outer housing 32 effective for the fluid reservoir 20 to hold up to about 0.15 liters (about 5.0 ounces) of fluid wherein additional fluid dumps out from the fluid reservoir 20 through the overflow outlet 23. Although the fluid reservoir 20 may be built to scale, for automobile applications a maximum fluid volume of the fluid reservoir 20 is from about 0.06 liters to about 0.12 liters (from about 2.0 ounces to about 4.0 ounces).

Whereas the overflow outlet 23 determines the maximum amount of available fluid in the fluid reservoir 20, the fluid volume sensor system 15 is operationally configured to activate the pump 14 as determined by the fluid level in the fluid reservoir 20. Once the pump 14 is activated, a predetermined volume of fluid is transferred from the fluid reservoir 20 to the conduit 22.

Suitably, the fluid volume sensor system 15 is in electrical communication with pump 14 whereby the fluid volume sensor system 15 is operable to activate the pump 14 once the fluid volume within the fluid reservoir 20 rises to a predetermined level. Suitable fluid level sensors 40 include, but are not necessarily limited to float-type switches, hydroelectric switches, pressure sensors/probes, and fluid level sensors/probes. A suitable electrical connection means between the sensors of the system 10 and the pump 14 includes those means known to persons of ordinary skill in electrical wiring, such as but not necessarily limited to electrical plugs, quick connects, and hardwire techniques such as wire splices, soldered connections, and crimp splices. As shown in FIG. 5A, the fluid reservoir 20 suitably includes a wiring access port 65 for receiving the system's 10 electric connections therein.

With reference to FIG. 3, in an embodiment of the fluid reservoir 20 where the fluid level sensor 40 includes a “float switch” as understood by persons of ordinary skill in the art of fluid level sensors, the fluid reservoir 20 suitably includes a baffle array 42 that partially encases or otherwise surrounds the float switch 40 to dissipate the wave energy of fluid housed within the fluid reservoir 20. In particular, the baffle array 42 is operationally configured to form a barrier around the fluid volume sensor system 15 to prevent the fluid level sensor 40 from erroneously activating and/or disabling the pump 14 as otherwise caused by fluid sloshing within the fluid reservoir 20 during vehicle use, e.g., an automobile driving along a bumpy road. Although not limited to any particular configuration, a suitable baffle array 42 is disposed along a vertical plane, whereby fluid may contact the fluid volume sensor system 15 by flowing underneath the baffle array 42. As shown in FIG. 3, the baffle array 42 may include a solid structure extending from the inner surface of the outer housing 32 to the solid barrier 36 effectively sealing off the float switch 40 along a substantially vertical plane. The baffle array 42 may also comprise one or more apertures there through as desired.

The float switch 40 suitably operates in a manner effective to provide an enabling electrical connection to the pump 14 as the float switch 40 rises to a predetermined height within the fluid reservoir 20 (see line A-A in FIG. 4). As shown, the maximum rise level of the float switch 40 (also referred to herein as the “activation level”) may be limited by either (1) the maximum fluid level of the fluid reservoir 20, or (2) the location of the overflow outlet 23. In a particularly advantageous embodiment, the activation level of the pump 14 may be set within a range from about level with the overflow outlet 23 to a predetermined minimum level below the overflow outlet 23, e.g., line A-A. As the float switch 40 drops below line A-A or to a predetermined level (see line B-B in FIG. 4), the electrical connection between the float switch 40 and the pump 14 is suitably broken, thus disabling the pump 14.

With reference now to FIGS. 7-10, simplified illustrations depicting how the baffle array 42 operationally prevents erroneous or non-requested pump 14 activity are shown. With particular attention to FIGS. 7 and 8, during vehicle use as fluid sloshes within the fluid reservoir 20 the float switch 40 rises to possibly erroneously activate the pump 14. However, when a baffle array 42 is employed as depicted in FIGS. 9 and 10, the baffle array 42 suitably forms a barrier against sloshing fluid allowing the pump 14 to receive accurate signals from the float switch 40 regarding the real time fluid volume within the fluid reservoir 20 to accurately activate and deactivate the pump 14. Suitable float type switches are commercially available from the following sources via the internet: www.suntekstore.com; www.gemssensors.com, www.aquahub.com, and www.meder.com.

Turning to FIGS. 11 and 12, the fluid volume sensor system 15 may include fluid level sensors in the form of probes spaced apart within the fluid reservoir 20, the probes being operationally configured to signal the pump 14 to activate/deactivate as the captured fluid reaches a predetermined level within the fluid reservoir 20. In this embodiment, a first sensor 43 is positioned along the inner surface of the fluid reservoir 20 establishing a pump 14 activation level including a maximum operational fluid volume within the fluid reservoir 20. A second sensor 44 is positioned along the inner surface of the fluid reservoir 20 establishing a minimum operational fluid volume within the fluid reservoir 20. As the fluid volume rises to contact the first sensor 43 (see FIG. 11) the first sensor 43 is operationally configured to activate the pump 14 to pump fluid out from the fluid reservoir 20 into conduit 22. As the fluid level drops below the second sensor 44 (see FIG. 12) the second sensor 44 is operationally configured to deactivate the pump 14. Once the pump 14 is deactivated, the fluid reservoir 20 can begin the refill process for future pump 14 activation.

In the embodiment of FIGS. 11 and 12, the first and second sensors 43, 44 are suitably sealed to the outer housing 32 in a manner effective to prevent fluid loss through the outer housing 32. In one non-limiting embodiment, the sensors 43, 44 are molded to the outer housing 32 using epoxy or silicone. Although not limited to any particular sensor configuration, suitable sensors 43, 44 include fluid level switches operationally configured to provide a signal output with regard to the presence or absence of a fluid. In terms of automobile usage, the sensors 43, 44 may include pressure sensors or switches, or in the alternative, liquid level sensors or switches commercially available from the following sources via the internet: www.suntekstore.com; www.gemssensors.com, www.aquahub.com, and www.meder.com.

In a particularly advantageous embodiment, a fluid level sensor 40 in the form of an optical liquid level sensor with an infra-red emitter and phototransistor may be employed (see FIG. 5B). As understood by persons of ordinary skill in the art of optical liquid level sensors, the fluid activation level of the pump 14 is suitably set at a level within the fluid reservoir 20 wherein the tip of the sensor 40 is immersed in fluid. Deactivation or inactivity of the pump 14 is suitably set when the tip of the sensor 40 is exposed to air. Suitable optical liquid level sensors may be acquired from SST Sensing, Ltd, United Kingdom; and Honeywell International Inc. With attention to FIGS. 5A and 5B, the pump 14 draws fluid from the first compartment 33 conveying the fluid through the valve 30 out from the fluid reservoir 20 to the conduit 22 where the fluid is directed toward the treatment member 16 and the outlet 18.

As illustrated in FIGS. 1 and 2, the conduit 22 fluidly connects the pump 14 to the outlet 18. In another embodiment, a separate second conduit may be implemented as a downstream conduit for fluidly connecting the treatment member 16 to the outlet 18. As known to persons of ordinary skill, the conduit 22 is suitably connected to fluid reservoir 20 and treatment member 16 via couplings or other fittings allowing for the release and/or replacement of the conduit 22, couplings, and other system 10 parts connected thereto.

Apposite conduit materials will become readily apparent to those skilled in the art, given the benefit of this disclosure. For instance, the conduit 22 may comprise any tubing effective for the transfer of fluid through the system 10. In addition, the conduit 22 may have any shape that is capable of transferring fluid through out the system 10. In one embodiment, the conduit 22 may be preformed for a particular application. In another embodiment, the conduit 22 may comprise flexible tubing. Non-limiting examples of suitable conduit materials include, but are not necessarily limited to metal alloys, glass, plastic, polymers, and combinations thereof. In a particularly advantageous embodiment, the conduit 22 is a flexible plastic hose or a silicone hose. Suitable fittings for securing the conduit 22 include but are not necessarily limited to zip ties and barbed fittings.

Concerning the treatment of captured fluid, the present system 10 is advantageous because it may be operationally configured to act upon captured fluid to provide one or more desired fluid end product(s). Although captured fluid may be treated through out the system 10, suitable treatment locations include, but are not necessarily limited to (1) the fluid reservoir 20, (2) the conduit 22, (3) one or more treatment members 16, (4) other additional reservoirs incorporated into the system 10, and (5) combinations thereof.

The captured fluid may be treated to provide one or more specific fluid products as desired. Thus, the type of treatment member(s) 16 employed may vary depending on the nature of the fluid initially captured and/or the desired fluid end product(s). Suitable treatment of the captured fluid may be accomplished according to one or more of the following techniques: (1) filtering the captured fluid to remove undesired fluid(s), undesired impurities, particulates, and/or undesired organic matter; (2) altering the temperature of the captured fluid; (3) altering the chemical constituency of the captured fluid; (4) altering the pH of the captured fluid; (5) separating fluid constituents into a plurality of post-treatment fluid streams, e.g., fluids having different viscosities; (6) altering the color of the fluid; and combinations thereof.

The type of treatment members 16 employed may vary depending on the desired fluid product. Suitably treatment members 16 may include, but are not necessarily limited to filter media, ionization systems, ultraviolet light emitting systems, heating elements, separators, fluid material additive containers, and combinations thereof. One exemplary filter or fluid material additive container is shown in FIGS. 13 and 14. In this embodiment as illustrated by arrows in FIG. 13, the filter is operationally configured to receive fluid from the conduit 22 and treat the fluid therein (or otherwise act upon the fluid as desired). Once treated, the fluid may be directed to (1) a second fluid reservoir 24, (2) outlet 18, or (3) another filter depending on the system 10 configuration.

With reference to FIG. 14, a suitable treatment member 16 comprises an outer housing 45 having an inlet 46 in fluid communication with the conduit 22 and an outlet 48 for treated fluid. In one embodiment, the outlet 48 may serve as the system 10 outlet 18. In another embodiment, the outlet 48 may lie in fluid communication with a conduit 22 configured to deliver treated fluid from the treatment member 16 to (1) a second fluid reservoir 24, (2) outlet 18, or (3) another filter as desired. Although the inner configuration of the treatment member 16 may vary, the treatment member 16 suitably includes one or more compartments operationally configured to treat fluid therein. As shown in FIGS. 13-15, the treatment member 16 is suitably oriented in a manner whereby the inlet 46 is set at a higher elevation than the outlet 48 to take advantage of gravity in addition to the conveyance forces generated by the pump 14 for dictating the fluid flow rate through the treatment member 16.

Depending on the intended use of the system 10, one suitable treatment member 16 intended to be mounted to a vehicle surface may be fitted with a corresponding mounting means 51 wherein the treatment member 16 suitably snap fits within the mounting means 51 as shown in FIG. 14. In automobile applications, the mounting means 51 is suitably releasably attached near the NC drip pan. For example, the mounting means 51 may be releasably attached to the fire wall or other substantially flat surface within the engine compartment of the automobile. The mounting means 51 may be attached to the automobile using one or more fasteners, adhesive tape, tie-wraps, or other tie type fasteners.

Referring to FIG. 15, the treatment member 16 may be operationally configured as a [fluid material additive+filter] combination for treating fluid passing there through. In this embodiment, the treatment member 16 suitably comprises at least two compartments 49, 50 separated by a partition 47. In this embodiment, the first compartment 49 is operationally configured to house one or more solid and/or gel like chemical components, the chemical component effectively acting on the fluid as the fluid enters the first compartment 49 wherein at least a portion of the chemical component is dissolved in the fluid. The second compartment 50 suitably comprises a one or more filters or membranes operationally configured to remove various substances from the captured fluid. Apposite filters or membranes are operationally configured to act on the captured fluid to remove various chemical constituents, undesired impurities, particulates, organic matter, and combinations thereof. In addition, the filters or membranes may be operationally configured to remove target fluids of particular densities.

As shown in FIG. 15, the partition 47 is operationally configured to separate two adjacent compartments. In a particularly advantageous embodiment, the partition 47 has an aperture means for the passage of fluid from the first compartment 49 to the second compartment 50. Suitably, the aperture means includes holes or slits effective to deny the passage of unwanted chemical additives and other particles that may otherwise clog the filter of the second compartment 50. The number of holes or slits in a particular partition 47 may vary depending on the intended use of the treatment member 16. For ease of manufacture, the partition 47 is suitably constructed from like materials as the housing 45, although this is not a requirement. In addition, the partition 47 may be releasably attached to the housing 45. In another embodiment, the partition 47 may include a mesh type material.

In the embodiment of FIG. 14, the treatment member 16 may be operationally configured to house one or more solid materials having particular chemical constituents as desired. While not limited to a particular configuration, solid chemical components are suitably provided in tablet form, pellet form, powder or granule form, block form, and combinations thereof, the number of solid chemical components housed within the treatment member 16 to vary as desired. Although the system 10 may be built to scale, a suitable treatment member 16 includes an inner housing of up to about a few inches in width and height depending on the chemical makeup of the tablet(s) and the intended use of the system 10. For example, where the tablets are intended to treat the captured fluid to produce windshield washer fluid to be directed to the windshield washer fluid reservoir, the tablets suitably have a width of up to about 3.81 cm (about 1.5 inches) and height of up to about 1.5 cm (about 0.59 inches). Suitable windshield washer fluid tablet products are commercially available from 303 Products, Inc., Palo Cedro, Calif.; and Chemplex Automotive Group, Inc, Fullerton, Calif.

The chemical components used may vary in chemical constituency depending on the intended use of the treated fluid of the system 10. For example, where the treated fluid is intended to be used as a windshield washing fluid for an automobile, the solid and gel like chemical components, e.g., tablets, suitably include (1) anti-freezing agents, (2) one or more components effective to dissolve and/or remove hydrocarbon residues such as petroleum derivatives, oils, fats, greases, sugars, and proteins, and combinations thereof from a vehicle windshield. In addition, where the treatment member 16 is operationally configured to provide an effective windshield washing fluid, the chemical components housed within the treatment member 16 may include, for example, detergents, pigments/dyes, solvents, anti-freeze, methylated spirits, and combinations thereof. Suitable solvents include methanol, ethanol, and combinations thereof. A suitable anti-freeze includes ethylene glycol and other commercially available anti-freeze chemicals. Each of the above listed components may be added to the captured fluid to provide a fluid end product effective for one or more of the following windshield washing applications: de-bugging, glass cleaning, as a rain repellant, and de-icing.

In another embodiment where the treated fluid is intended to be used as a radiator additive for an automobile, the solid and gel like chemical components within the treatment member 16 suitably include anti-freeze, rust inhibitors, rust removers, and combinations thereof. A suitable rust inhibitor or rust remover includes, but is not necessarily limited to phosphoric acid. In an embodiment where the captured fluid is H₂O intended as potable H₂O, the first compartment 49 may house activated carbon or activated charcoal as the terms are known in the art. The treatment member 16 may also include a filter for removing impurities from the H₂O prior to the H₂O being directed through outlet 18. In another embodiment where the captured H₂O is intended as potable H₂O, the treatment member 16 may include a reverse osmosis filter system.

With further reference to FIG. 15, filter media housed within the second compartment 50 suitably comprises a lattice structure operationally configured to prevent unwanted materials from exiting through the outlet 18. Without limiting the invention, suitable filter media include, but are not necessarily limited to filter paper, non-woven fabric, felt, and other materials having porous or semi-permeable membranes. In an embodiment of a filter constructed for automobile use, a suitable filter may remove unwanted particles while allowing added chemicals to pass there through. Suitable filter materials include those commercially available filters known to persons of ordinary skill in the art including, but not necessarily limited to filters constructed from woven fibrous material, non-woven fibrous material, fine mesh material, plastics, ceramics, charcoal cloth, polymeric fibrous pulp, foamed material, and combinations thereof. For commercial purposes, it is contemplated that the housing 45 may be replaced once the chemical components of the first compartment 49 and/or the filter media of the second compartment 50 have reached their usable life. It is also contemplated that the first compartment 49 may be refilled with chemical components as necessary, and that the filter media of the second compartment 50 may be replaced as necessary.

As shown in FIG. 15, the treatment member 16 may also comprise an air vent 52 for pressure equalization within the housing 45 to aid the flow of fluid from inlet 46 to outlet 48. One suitable embodiment of an air vent 52 is depicted in FIG. 16. In this embodiment, the air vent 52 includes a continuous wall member 54 operationally configured to house a biased member 55, a screen 56, and a diaphragm valve 57 therein. In a particularly advantageous embodiment, the wall member 54 includes a tubular configuration, the biased member 55 includes a compression spring, wherein the screen 56 has at least one aperture permitting at least some air flow there through. Although not limited to certain materials of construction, the wall member 54 and screen 56 are suitably constructed from similar materials such as plastics, metals, and combinations thereof. In operation, the air vent 52 is activated by a suction created as fluid travels toward and/or through outlet 48 allowing air to enter the housing 45.

The housing 45 may be manufactured using known techniques similar to those described above with reference to the fluid reservoir 20. Similarly, the housing 45 is suitably constructed from materials including, but not necessarily limited to those materials resistant to chipping, cracking, excessive bending and reshaping as a result of ozone, weathering, heat, moisture, other outside mechanical and chemical influences, as well as impacts. In particular, a suitable housing 45 may be constructed from materials including, but not necessarily limited to metals, plastics, fiberglass, plexiglass, filled composite materials, and combinations thereof. In a particularly advantageous embodiment, the housing 45 is constructed from plastic.

As previously stated, fluid may flow out of the system 10 once processed, or the fluid may be conveyed to one or more post-treatment fluid reservoirs for future use. With regard to automobiles, suitable post-treatment fluid reservoirs include, but are not necessarily limited to windshield washer fluid reservoirs, radiator overflow fluid reservoirs, potable water reservoirs, and water reservoirs for hydrogen generation.

With reference to FIG. 2, a system 10 operationally configured to convey processed fluid to a windshield washer fluid reservoir 24 suitably includes (a) a pump 14, (b) a fluid volume sensor system 15 within the fluid reservoir 20, (c) a fluid volume sensor system 70 within the windshield washer reservoir 24, and (d) a power source 58 having a positive terminal and a ground, all of which is connected to control circuitry 200. As shown, reservoirs 20, 24 are in electrical communication with the pump 14 via control circuitry 200 in a manner effective to promote optimal system 10 operation while safeguarding against non-requested operation of the pump 14 during vehicle use.

FIG. 17 shows a schematic of representative control circuitry 200 as provided via a circuit board. Control circuitry 200 may include the above mentioned components, as well as one or more fuses, an optional power switch, an optional temperature switch, an optional timer relay to delay pump 14 activation and/or determine the time for pump 14 operation once activated, a flow switch, and an optional operator signaling means, which in a particular embodiment may all lie in communication with a relay terminal. The fuses and switches include those known to persons skilled in electronic circuitry.

Where the present system 10 is designed for automobile use, the automobile may be fitted with an operator signaling means in the form of one or more light sources and audible signals suitably installed in the automobile dashboard, driver side door panel, or middle seat console. A suitable light source includes light emitting diodes (“LED”). In an embodiment of the system 10 operationally configured for the manual capture and processing of fluid for refilling a windshield washer fluid reservoir 24, an automobile may be manufactured to include some form of warning signal such as a light source and/or audible signal to indicate when the fluid level of the washer fluid reservoir 24 is sufficiently low or drops to a predetermined level. In addition, an automobile may be fitted with a first signaling means to indicate when the system 10 is powered on/off, and a second signaling means to indicate when the pump 14 is actually pumping fluid—both of which compliment the preexisting fluid level indicator provided by the automobile manufacturer.

With further reference to FIG. 17, persons of ordinary skill in the art can appreciate the various relays of the control circuitry to open and close in a manner effective to accomplish one or more of the following functions: (1) setting the pump 14 to an OFF position when both the fluid reservoir 20 and second fluid reservoir 24 have sufficient fluid levels, (2) setting the pump 14 to an ON position when both the fluid reservoir 20 and second fluid reservoir 24 have insufficient fluid levels thereby activating the pump 14, (3) setting the pump 14 to an OFF position when both the fluid reservoir 20 and second fluid reservoir 24 are empty or have low fluid levels, (4) setting the pump 14 to an OFF position when the fluid reservoir 20 has a low fluid level (or empty) and the second fluid reservoir 24 has a sufficient fluid level, (5) setting the pump 14 to an OFF position when the ambient temperature of the system drops to about freezing, and (6) setting the main switch of the system 10 in an OFF position. Table 1 below provides a parts list for a representative circuitry printed circuit board of FIG. 17.

Although the output voltage may vary depending on the vehicle and/or the application of use, a suitable output voltage of an automobile type power source is about 12 volts D.C. A system 10 designed for automobiles may include a lead-acid battery as the power source.

A power switch may be incorporated into the system 10 as desired. Thus, in one aspect of operation the system 10 may be wholly automated, whereas incorporation of a power switch allows the system 10 to be controlled manually. The power switch may be selected from switches well known to those of ordinary skill in the art, including for example, bush-button switches, a toggle switches, rocker switches, and slide switches. Although the placement of the power switch may vary, the power switch is suitably located in convenient proximity to the vehicle operator in like manner as other control panel objects. In an automobile for example, the power switch may be located on the dashboard, driver side door panel, or middle seat console. In operation, the power switch allows the vehicle operator to selectively operate the system 10—deciding whether he/she wants the system 10 on or off.

Another advantage of the present system 10 includes the option of a temperature switch to control the system 10 usage during cold weather conditions, wherein once the ambient temperature of the system 10 has reached about 0° C. (about 32° F.), the temperature switch is operationally configured to deactivate the system.

It is also contemplated that in one embodiment of the invention, a pump 14 time delay means of the system 10 may be controlled by a time delay chip as known to persons of ordinary skill in electronics.

It is also contemplated that in one embodiment of the invention, a filter or similar item may be placed at a point between the fluid reservoir 20 and the pump 14 whereby the filter or similar item is in fluid communication with both the fluid reservoir 20 and the pump 14 as a further treatment means of the fluid.

It is also contemplated that in one embodiment of the invention, an in-line check valve may be incorporated in the conduit 22 at a point between the pump 14 and the treatment member 16.

The invention will be better understood with reference to the following non-limiting examples, which are illustrative only and not intended to limit the present invention to a particular embodiment.

Example 1

In a first non-limiting example of the system 10 operationally configured to capture water condensate from an automobile A/C, process the water, and convey the processed water to the automobile's windshield washer fluid reservoir 24, the system 10 comprises the features discussed below.

The pump 14 of the system 10 will run automatically once the captured water condensate within the fluid reservoir 20 rises to at least the level of the optical liquid level sensor 40. The pump 14 will continue to run for approximately twenty-five seconds until the water volume within the fluid reservoir 20 is substantially drained, or until the fluid level in the automobile's windshield washer fluid reservoir 24 has risen to at least the level of the fluid volume sensor system 70 within the windshield washer reservoir 24.

A/C—System Interface

Fluid communication between the automobile A/C and the system 10 is achieved via an inlet member 12 comprised of a rubber nipple at a first end operationally configured to fit any condensate pan drip hole transfer tubing having a diameter from about 0.95 cm to about 1.9 cm (about 0.375 inch to about 0.75 inch). Sealable passage of condensed water from the A/C to the fluid reservoir 20 is accomplished by orienting the through hole at the bottom center of the nipple. The opposing side of the inlet member 12 operationally configured to mate with the fluid reservoir 20 is provided with a second nipple suitably manufactured from a resilient yet durable rubber or plastic effective to withstand normal engine compartment and outdoor operating temperatures. Suitably the second nipple is a tubular type nipple having an outer diameter of about 0.95 cm (about 0.375 inch). Water will be delivered to the fluid reservoir 20 through this connection. Once the volume of water in the fluid reservoir 20 rises to at least the level of the optical liquid level sensor 40, the pump 14 is operable to run for approximately twenty-five seconds, draining the fluid reservoir 20 conveying the water to the conduit 22.

Run the power wiring harness from the fluid reservoir 20             to the automobile battery securing the wiring to             substantially low temperature items of the automobile.             Install the BLACK (−) wire terminal connector to ground and             the RED (+) wire terminal connector to the positive pole of             the battery.

The system 10 is now installed and will start operating automatically once the fluid reservoir 20 receives condensate water from the A/C when the automobile is running. Suitably, the instant filter 16 produces about 18.9 liters (about 5.0 gallons) of windshield washing fluid and filters out particulates that may collect in the system. Once the detergent in the filter 16 is spent, the system 10 continues filtering particulates from the water. To avoid algae or other build up or clogging within the filter 16, the filter 16 should be cleaned or changed once the filter 16 is spent of chemicals or once every six months.
